Haworthia janseneana

Haworthia janseneana was described by Uitewaal in the 1940s from a cultivated plant and is almost certainly of garden origin, a hybrid or selection in the hard-leaved Haworthiopsis group; it has no wild records. Grow it like a zebra plant: bright softened light, cool nights, a mineral mix and thorough drying between waterings.
